I use Quantums because they are a compact kit that provides a lot of pop on the road for me without bringing my Buff lights and vagabonds.
They are rugged and versatile but I do believe their success will be their undoing as the Chinese are beginning to knock them off (Godox) like they have Bowens, and Hensel . Not to their level of quality yet but will be in a short time.
To copy the light Ellen is using does not need a Quantum, just a medium speedlight as it is in direct, unmodified form. As UKphotographer said it is just providing a fill to an HMI lit scene. The real drama is not in the photogrpahy but in the scene. Do not get confused by the glitz of the models and the location. The finals will have a real crime scene look to them which, by there very nature, are only rough approximations of accurate exposure.
Not a criticism, just an observation of the style that is currently enjoying favor.
